ECU Pinouts for Toyota 4A-GZE ECU
MAP 8.9:1 Compression with DLI
Car Model: AE101?
Toyota Part Number: 89661-12790
Denso Part Number: 175700-3371

  • The "TOP OF THE ECU" refers to the side with the orange sticker which reads "4AGZE".
    It is also the side of the ECU which can be removed to reveal the circuit board inside!

  • Pins whose locations are different from those in the other MAP GZE ECU as listed on Club4AG.com's GZE pin out
    have their CODE, PIN NUMBER and DESCRIPTION in bold.
  • Pins which are not used but do have a function in the other GZE ECU  as listed on Club4AG.com's GZE pin out
    are marked with equal symbols "= = =".
  • Pins whose IDs are slightly different from other GZE ECU as listed on Club4AG.com's GZE pin out
    have just their IDs in bold.
  • The EVP pin in 16 pin plug is not listed on Club4AG.com's GZE pin out.
    This could be a mistake on Moto's part, or, perhaps it is simply not on the other MAP GZE ECU.

 

Colour Scheme/Leged:
R = Red, W = White, G = Green, B = Black, Blue = Blue, V = Violet (or blue), BR = Brown, LG = Light Green?
What I call BLUE, Moto-P calls VIOLET. I could be wrong in my perception of the wire colour.

Y-G means a yellow wire with green stripe. G-Y means a green wire with yellow stripe.
Y-G is not the same as G-Y. This syntax carries for all listed wires.

No one is helping me out online here so don't blame me for any mistakes made as a result of this page.

 

  • The ECU pin outs for this MAP GZE ECU were obtained by myself by opening the ECU cover and reading them off the printed circuit board within. From the information below you can see that the ECUs
    Y connector (22 pin) is the same in layout as the other MAP GZE ECU listed on Club4AG.com's GZE pin out.

  • The 22 pin plug itself is missing so I cannot give the wire colours. Sorry.
    Ive left in the Club4AG colour scheme for the 22pin plug in case they are the same.
    The  16pin and 26 pin plugs colours schemes ARE correct as these two plugs were on the loom we have!
  • However the 16pin and 26 pin plugs show several differences. The G- pin is not in the 16pin plug, it is moved to the 26pin plug. Also several of the 26pin plugs functioning pins have been relocated.
    These are, all the DISTRIBUTOR PINS, ROTARY SOLENOID (whatever that is?) and the FUEL PRESSURE UP.
